Webber writes off Mercedes team

Ferrari, McLaren and Red Bull have each claimed a victory this season while Mercedes GP's best result was a third-placed finish for Nico Rosberg at the Malaysian GP. Added to that, Merc have just one driver firing at the moment as Michael Schumacher struggles to get up to speed whereas Ferrari, McLaren and Red Bull each have two drivers bringing in solid points.

The result is that Ferrari are leading the Drivers' and Constructors' Championship with McLaren and Red Bull hot on their heels. Merc are 32 points off the pace in the battle for the teams' title.

"Mercedes are doing completely okay but it's Ferrari, McLaren and Red Bull who are the most consistent at the moment," Webber told Bild.

He added: "The fight is clearly between these three teams."
